Short answer: Most likely, but not from day 1.
I try to add support for popular maps that change the animal setup, like the current Hof Bergmann. However I have to actually have access to the maps to be able to see if support can be added an add it. Some might be hard/impossible to support, but most probably can be supported without too much work.
The same goes for the cattle breed pack. It should work, but it depends on what the map changes.
